The development of version 9.1 of the open source PostgreSQL SQL database is approaching completion; the new version is expected to be finalised before the end of September 2011. The developers say that the first release candidate, which has just been issued, fixes all of the bugs that were reported during beta testing, but that no further new features have been added.
